We describe a new butterfl y species, Anaeomorpha mirifi ca Simon and Willmott, n. sp. (Lepidoptera, Nymphalidae, Charaxinae), from premontane rain forest of the Chocó region of northwestern Ecuador. This represents the second known species and the fi rst record outside of the Amazon basin for this taxonomically and biologically enigmatic genus. Although the two species are not known to be sympatric, we identifi ed 21 characters in the external color pattern, wing shape and male genitalia that together support distinct species status. Most notably, the new species possesses an ocellus in the ventral hind wing tornus, a character which occurs in the Neotropical Charaxinae only in the genus Prepona Boisduval, 1836. A mean divergence of 6.8% in the COI ‘barcodes’ between the two species underlines their taxonomic distinctness.
The existence of complex clauses in the Amazonian language Pirahã has been controversially debated. We present a novel analysis of field data demonstrating the existence of complex clauses in Pirahã. The data concern the tone of the morpheme 'sai' and stem from a field experiment where a second language speaker of Pirahã presented sentences and Pirahã speakers were asked to correct them saying the correct sentence alound. The experimental items contained the morpheme 'sai' in two different clausal environments: a nominalizer and a conditional environment according to Everett's 1986 description. Our phonetic analysis shows an effect clausal clausal environment on the pitch of 'sai'. The native Pirahã speakers pronounced conditional 'sai' with lower pitch than nominalizer 'sai'. We show furthermore that the experimenters pitch on 'sai' shows the opposite pattern from that of the native Pirahã speakers and hence the Pirahã's pitch could not just have been copied. The effect of the clausal environment on the tone of 'sai' can be explained by a complex clause analysis of Pirahã, while existing alternative proposals do not explain the difference.
